Needle for a needle bar or rod for textile combing machines, and a needle bar with such needles, as well as a method for attaching or replacing an outfit of such needles

Abstract

In a needle for a needle bar or rod, the needle comprising a fastening area at its foot and above this an actively combing tip area, the needle being a stamped element and the fastening area having a recess closed or open outwards for the needle to be slipped on a support rod, the recess being non-circular or having projections or indents corresponding to the cross-section of the support rod such that the needle is disposed non-rotatably on the support rod, it is provided, with a view to convenience of replacement and simplicity of design of a needle bar, that for textile combing machines, in particular drawing equipments, for intersecting machines, feed combs, top combs, round combs or the like, the tip area is distinctly higher than the fastening area and is made approximately oval in cross-sectional shape by stamping.

What is claimed is: 
     
       1. A needle for mounting on a support rod for use with textile combing machines, the needle (1) comprising a foot portion having a fastening area (3) and a single actively combing tip (2) formed on and projecting from the foot, the needle being a stamped element and the fastening area (3) having a first recess (4) for permitting the needle (1) to be slipped on a support rod (10), the first recess (4) and the support rod (10) having engagement means for slidable, non-rotatable engagement between the recess and the support rod (10), wherein on textile combing machines the tip (2) projects significantly above the fastening area (3) and is made approximately oval in cross-sectional shape by stamping. 
     
     
       2. A needle according to claim 1, wherein the first recess opens outward through the fastening area (3). 
     
     
       3. A needle according to claim 1, wherein the first recess is enclosed by the fastening area (3). 
     
     
       4. A needle according to claim 1, wherein said engagement means comprises the first recess which is non-circular and has indents corresponding to the cross-section of the support rod (10). 
     
     
       5. A needle according to claim 1, wherein said engagement means includes the first recess which is circular and has projections (8) corresponding to the cross-section of the support rod. 
     
     
       6. A needle according to claim 1, wherein the first recess (4) is approximately oval. 
     
     
       7. A needle according to claim 1, wherein a second recess (6) is provided beside the first recess (4) to permit the needles (1) to be lined up prior to being mounted on the support rod (10). 
     
     
       8. A needle according claim 1, wherein a number of the needle are engaged on the support rod to form a line of needles. 
     
     
       9. A needle according to claim 5, wherein the support rod (10) has at least a longitudinal groove (11) for a corresponding projection (8) of the needle (1) to engage with. 
     
     
       10. A needle according to claim 8, wherein the fastening area (3) of each needle of the line of needles is bedded at least partially in a plastic body (7). 
     
     
       11. A needle according to claim 10, wherein the plastic body (7) forms an interspace between two adjacent needles of the line of needles (1). 
     
     
       12. A needle according to claim 8, wherein each of the line of needles (1) has an enlarged fastening area (3e). 
     
     
       13. A method for attaching needles to a support bar of a textile combing machine comprising, forming a number of needles having a fastening area and a combing tip projecting form the fastening area, providing the fastening area with a recess for engagement with the support bar, mounting the needles on an assembly tube having approximately the same cross-sectional size as the support bar, aligning the assembly tube with the support bar and transferring the needles from the assembly tube to the support bar. 
     
     
       14. A method according to claim 13, wherein the needles are mounted on the assembly tube for storage and later use.
